Nick Kledzik 23bbd617e4 <rdar://problem/12512722> Use arm divide instruction if available

Chandler Carruth 6acfaaf3aa Remove the old, and non-functional CMake build system from CompilerRT. 
I cannot build any part of this successfully on either Linux or Darwin,
and the replacement is worlds simpler by requiring that this be built as
a subproject of LLVM. If this breaks you for any reason, please let me
know, and let me know what your use case is.

Daniel Dunbar 2003d39f7c build: Add ModuleName per-subdir variable as a way to organize the different 
sets of functions/objects into high level groups. Currently we have "builtins"
(the main compiler-rt code), "profile", and "asan".
 - Use this to define CommonFunctions and ArchFunctions to only reference the
   builtins functions.

Stephen Canon 5abb5c14c4 Carefully written implementations of the 32-bit integer divide and modulus functions for ARM. These are still using a naive digit-by-digit algorithm, but the core loop has been carefully written.
